Combat Response Training Tester Based on Intelligent Force-Measuring Sensor and Digital Circuit

Abstract

In combat sports, the team members take attack and defense as the core of sports, and the technical movements are not periodic and the application process is irregular. During the competition, observe the opponent’s neutral position, judge timely, and react quickly. At the same time, athletes are required not only to master skilled technical movements but also to have rapid and accurate adaptability. In order to improve athletes’ rapid response ability, according to the rapid response training scheme, a combat response training tester based on a force-measuring intelligent sensor and digital circuit is designed to improve the athletes’ response ability. Firstly, a comprehensive test system of combat trainer is designed based on the intelligent force-measuring sensor and MSP430, which can measure the response time, speed, and strength of boxing. Secondly, a wavelet filtering algorithm is used to filter the sensor measurement data. Finally, the striking force and striking time of each action are recorded by sensors and data acquisition devices to reflect the striking effect and reflect the “accurate” objectives of the project characteristics. Based on the noninterference and anti-interference of e-touch piezoelectric film, it can be made into universal force-measuring sensors of different specifications for fight competitions according to needs. After being connected into a module network in parallel, it can be connected with the microcontroller to determine the hit area. In addition, the team reaction training test device has laid a foundation for the scientific evaluation of improving the team members’ reaction ability and attack defense conversion ability. The launch of the comprehensive ability tester for combat athletes introduces the previous fuzzy evaluation of athletes’ comprehensive ability into a new way of scientific quantitative measurement and evaluation, which will provide a scientific basis for the selection of combat vibration items, the regulation of training process, the inspection of training effect, and the formulation of enrollment and examination standards for sports colleges and universities. The results show that the instrument can obtain the parameters of hitting strength, strength endurance, hitting speed, speed endurance, hitting impulse, and hitting power of sports biomechanics on the group of fighting events, which provides a reliable basis for coaches to implement teaching and training for athletes.
